No one is against having fun. What we are against is the satanic and wiccan elements of these things, in a climate where the Christian meaning of Christmas and Easter are systematically driven out.

Which is the main point. The danger isn't that by dressing up and getting candy one day a year would lead to a child becoming pagan, but that the society is promoting a kind of agnostic polytheism. When you see show after show and book after book glorifying witchcraft, a Christian parent needs to be aware and guard their children against that.

"Agnostic polytheism" is neopaganism.
